I too early pass it to resolved the bolded values don't work on page load but with button they work ? What i have done wrong ?

 

<script type="text/javascript">    
dojo.require("dijit.ProgressBar");

var progressBarSetValue = function(){

    var maxIloscID = '#{javascript:getClientId("maxIloscRozwiazan_Ankieta1");}'; <--- This lane write simple string to maxIloscID not value
    //var maxIloscID_Value = document.getElementById(maxIloscID).value;
    var iloscID = '#{javascript:getClientId("iloscRozwiazan_Ankieta1")}'; <--- This lane write simple string to iloscID not value
    //var iloscID_Value = document.getElementById(iloscID).value;
    jsProgress.update({ maximum: 100, progress: maxIloscID_Value/iloscID_Value });
}  
dojo.addOnLoad(progressBarSetValue);
</script>

 

Resolved by putting script on page event: onClientLoad
